Sentinel Peak, Tucson

The locals commonly refer to this high elevation peak, just west of downtown, as "A" Mountain because since 1915, University of Arizona students have whitewashed the letter "A" on its eastern slope. Its history, however, goes much further back: it was at the foot of this mountain that the earliest traces of human settlements in the Tucson area were found. The top of the mountain offers one of the best panoramic views of the Tucson basin, as well as a few BBQ grills.
